Hi,

I think there’s flaw in your script:
if [ -e /tmp/$externip ] ; then
echo No IP Update Required ;

If your wan link reassigned to an ip that have been assigned but have been replace to another ip address, than no modification to your asterisk configuration will be made.

since /tmp/$externip will never removed

I’ve make slight modification:

if [ `ls /tmp/ac*` = "/tmp/ac$externip" ] ; then
echo No IP Update Required ;
else
echo IP Update Required ;
rm -f /tmp/ac* ;
touch /tmp/ac$externip ;
echo "externip=$externip" > /etc/asterisk/sip_custom.conf
echo "localnet=$localnet/255.255.255.0″ >> /etc/asterisk/sip_custom.conf
asterisk -rx "dialplan reload" ;
fi

Regarding virtualization, there have been a number of problem reports using VMWare under Linux on multi-core CPUs — the virtual machines have a tendency to lose time. I struggled with the various solutions posted on VMWare’s site and elsewhere on the internet, but the only usable solution I could find was to run a process every minute to synch the VM’s time with an NTP (time) server. The lost time caused all kinds of problems with dropped audio, noisy calls, missed phone keypresses, etc. For PBXiaF, I heartily recommend using a cheap PC rather than trying to go virtual.

Regarding Virtualization. Thanks for the advice, unfortunately I am on the UK and we don’t have the Wal-Mart $199 Everex special and even if we did it would cost £199 or approx $400 plus tax. (I live in "rip-off Britain"). However, following your advice I will look instead for a cheap new motherboard/cpu etc..to replace my old homebrew setup and install pbx-in-a-flash on its own dedicated machine. Again though are there any real benefits/issues with the 64 bit iso and say a dual core cpu? Thanks for the help. [WM: For a huge system handling hundreds of users and dozens of simultaneous calls, there is certainly an advantage in a 64-bit install, but for most folks you'll be fine with the 32-bit system and a meg or two of RAM depending upon usage volume.]

I will be replacing in the next two weeks my aging trixbox homebrew setup with a new 64bit system which I wish to run as a virtualized machine. The virtual multi-operating systems will use Windows XP, Windows Vista, PBX-in-a-flash, and a general Linux op – possibly fedora, suse or ubuntu. The hardware will comprise a quad core processor and 8 mb of memory and trunks for the pbx will be linksys spa 3102’s and several voip trunk providers and softphones on networked pc’s (local and remote over the internet). Do you foresee any problems with this approach and which pbx-in-a-flash iso should I use (64 bit preferred)?

[WM: We don’t recommend running PBX in a Flash under VMware for a production environment particularly when it runs flawlessly on a $199 WalMart Special.]

Will there be an update path from PIAF 1.1 to 1.2 that does not require a complete re-install (i.e. one that preserves the current configuration) ????

Thanks!

[WM: If you’ve run update-sources and update-scripts, you’re already there. We obviously can’t change you up to 64-bit processing, and the upgrade to Asterisk 1.6 is wobbly. But you’re not missing much there at the moment. Other than that, you’re current.]
